407 Deprecate the entire library. Merged years ago to provide compatibility
408 with Libav, it remained unmaintained by the FFmpeg project and duplicated
409 functionality provided by libswresample.
411 In order to improve consistency and reduce attack surface, it has been deprecated.
412 Users of this library are asked to migrate to libswresample, which, as well as
413 providing more functionality, is faster and has higher accuracy.

754 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
756 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be

824 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
825 the reset of the ASS ReadOrder field on flush. This affects the content of
826 AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
829 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
830 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
831 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
832 The default value for this option will change to "ass" at the next major
833 libavcodec version bump.
835 The current default is "ass_with_timings" for compatibility. This means that
836 all subtitles text decoders currently still output ASS with timings printed
837 as strings in the AVSubtitles.rects[N]->ass fields.
839 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
840 timing is limited to a 1/100 time base, so this is relevant for any subtitles
841 format needing a bigger one), ease timing adjustments, and prevents the need
842 of removing the timing from the decoded string yourself. This form is also
843 known as "the Matroska form". The timing information (start time, duration)
844 can be found in the AVSubtitles fields.

3244 Remove the next field from AVFilter, this is not anymore required.
3246 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3247 Introduce the avfilter_next() function.
3249 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3250 Change the signature of avfilter_register() to make it return an
3251 int. This is required since now the registration operation may fail.
3253 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3254 Make the pixdesc.h API public.
3256 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

3273 Add w and h fields to AVFilterPic.
3275 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

3278 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3279 Add a pts field to AVSubtitle which gives the subtitle packet pts
3280 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3281 not work right without this.
3283 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3284 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3285 major version. Use AV_PKT_FLAG_KEY instead.
3287 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3288 av_lockmgr_register() can be used to register a callback function
3289 that lavc (and in the future, libraries that depend on lavc) can use
3290 to implement mutexes. The application should provide a callback function
3291 that implements the AV_LOCK_* operations described in avcodec.h.
3292 When the lock manager is registered, FFmpeg is guaranteed to behave
3293 correctly in a multi-threaded application.
3295 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3296 av_free_packet() is no longer an inline function. It is now exported.
3298 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3299 Please use NULL instead. This has been supported since r16506
3300 (lavf > 52.23.1, lavc > 52.10.0).
3302 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3303 The old decoding functions are deprecated, all new code should use the
3304 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3305 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3306 argument instead of a const uint8_t *buf / int buf_size pair.
3308 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3309 Introduce the av_fifo_space() function.
3311 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3312 Move AVPacket declaration from libavformat/avformat.h to
3313 libavcodec/avcodec.h.
3315 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3316 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3317 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3318 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3319 PIX_FMT_BGR32_1 are now macros.
3320 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3321 Re-sort the enum PixelFormat list accordingly.
3322 This change breaks API/ABI backward compatibility.
3324 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3325 Add the enum PixelFormat values:
3326 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3327 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3329 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3330 The Mersenne Twister PRNG implemented through the av_random* functions
3331 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3334 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3335 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3336 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3337 and av_fifo_realloc2.
3338 In addition, the order of the function arguments of av_fifo_generic_read
3339 was changed to match av_fifo_generic_write.
3340 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3341 applications, they may not use sizeof() or directly access members.
3343 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3344 Introduce a new metadata API (see av_metadata_get() and friends).
3345 The old API is now deprecated and should not be used anymore. This especially
3346 includes the following structure fields:
3347 - AVFormatContext.title
3348 - AVFormatContext.author
3349 - AVFormatContext.copyright
3350 - AVFormatContext.comment
3351 - AVFormatContext.album
3352 - AVFormatContext.year
3353 - AVFormatContext.track
3354 - AVFormatContext.genre
3357 - AVProgram.provider_name
